Typical complement: 834-1085
Estimated cost, $5.159 million (£1.290 million)
Remarks:
Oil firing.
Relative extent of belt armor, 40 percent of 'typical' coverage.
Main belt does not fully protect magazines and
engineering spaces.
Ship has slow, easy roll; a good, steady gun platform.
Excellent seaboat; comfortable and able to fight her guns
in the
heaviest weather.
Magazines and engineering spaces are roomy, with superior
watertight
subdivision.
Ship is roomy, with superior accommodation and working space.
Main deck secondary guns subject to being washed down
in a seaway.
